Hi all,

I want to build a url like this: [name.site.com](http://name.site.com) . Can RoR read out the  
name in the url? If not I supose it’s uo to the webserver. Can webrick  
or Mongrel use this and pass this to RoR. I need the name in the url  
since it will define what will be shown on the page.

Thanks  
Stijn

I dont know exactly how it would be done, but i am sure that it can be  
done. Take the [USERNAME.highrisehq.com](http://USERNAME.highrisehq.com) thing 37signals got going.

How you integrate it with url\_for? So :controller =\> ‘account’,  
:action =\> ‘home\_page’, :id =\> user.login goes in, and a virtual host  
URL comes out?
